I’m trying to make something in 2d where once the player reaches the end of the level, they’re back at the beginning and it just keeps going like that. I could imagine how this could be done in terms of setting the player position, but if I have a scrolling parallax background, how would I make that match up reliably?

    Do you want the background to have looped back to the start after one cycle? If so, you probably have to make it repeat N times more than the foreground, and move by a factor of 1/N in comparison to the foreground. Or put another way, have 1/N times the length. That means that after one cycle, the background has moved a distance of 1/N, but also repeated exactly once.

    I hope this makes sense…
